I cashed in some BA miles for two CX flights...first one LAX to HKG in J, and second one for HKG to SIN in F. Only a hour and ten minute connection time in HKIA. I assume I can check in for both flights at LAX, but is this risky? Don't want to ruin the start of our vacation if LAX flight is late. The SIN flight is the last one of the day, so if I miss, would I have any difficulties rebooking for next day? I realize possibly my F might be in jeopardy...Thanks for the help and insights.
